Abstract

The wild species of rice (Oryza minuta) containing BBCC genome was crossed with three varieties of cultivated species (Oryza sative) : IR70, IR72 and IR74 having AA genome. The seed formation from these crosses were between 9.33 - 20.28%. The immature embryos from the 9-14-day-old seeds could grow into plantlets on the MS agar medium supplemented with 1 g/1 yeast extract and 2-3 mg/1 BAP. The two hybrids which were transferred to grow in a natural condition showed the same plant type as their parental cultivated varieties but their panicles and seed shapes were similar to the wild species. Seeds were not produced in any of these hybrids.
